British International bought a 24 seater Sikorsky helicopter up to Cheshire from Cornwall. Their team ensured all project staff were fully briefed for the task at hand, and the National Trust wardens worked with a team of fantastic volunteers to marshal the exclusion zone around Crow Wood and the car park tower construction area.
The lifts for the 9m towers were completed with relative ease. The weather was very poor which made life less than favourable for the marshals, but in actual fact the helicopter required windy conditions to achieve the required levels of uplift. Due to the weight of the towers, the helicopter had to be refuelled after each lift in order to keep on-board weight to a minimum.
The lifts for the two 12m towers proved slightly trickier as they were even heavier than the others. The sheer weight of the towers meant that they needed to be partially deconstructed to enable the helicopter to lift them up and carry them into place safely.
